Driving tips G Warning G Warning 153 ! Vehicles with 4MATIC: a function or performance test may only be carried out on a two-axle dynamometer. If you are planning to have the vehicle tested on such a dynamometer, contact an authorized Mercedes-Benz Center to obtain further information first. Otherwise, the drive train or the brake system may suffer damage. ! Vehicles with 4MATIC: as the ESP® system operates automatically, the engine and the ignition must be switched off (SmartKey in position 0 or 1 in the ignition lock or Start/Stop button in position 0 or 1) while the parking brake is being tested on a brake dynamometer. Braking maneuvers triggered automatically by ESP® may seriously damage the brake system. ! Vehicles with 4MATIC: as the ESP® system operates automatically, the engine and the ignition system must be switched off (SmartKey in position 0 or 1 in the ignition lock or Start/Stop button in position 0 or 1) when: Rtesting High-performance brake system for AMG vehicles The high-performance brake system is only installed on the C 63 AMG. G Warning New vehicle brake pads and discs, and replacement brake pads and discs may take several hundred miles of driving until they provide optimum braking efficiency. Until that time, you may need to use increased brake pedal pressure while braking. Please be aware of this and adjust your driving and braking accordingly during this break-in period. Excessive high-demand braking will cause correspondingly high brake wear. Please be attentive to the brake warning lamp in the instrument cluster and brake condition messages in the multifunction display. Especially for high performance driving, it is important to maintain and have the brake system checked regularly. The high-performance brake system is designed for heavy loads. This may lead to noise when braking. This will depend on: Rspeed Rbraking the parking brake on a brake dynamometer. Ryou intend to have the vehicle towed with the front axle raised. Braking maneuvers triggered automatically by ESP® may seriously damage the brake system. If your brake system is only subjected to moderate loads, you should regularly test your brake system's function by forcefully depressing the brake pedal when driving at high speed. This will give the brake pads better grip. force Renvironmental conditions, such as temperature and humidity The wear of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driving style and operating conditions. Z Driving and parking If other than recommended brake pads are installed, or other than recommended brake fluid is used, the braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired. This could result in an accident. Make sure that you do not endanger other road users when you apply the brakes. You can find a description of Brake Assist (BAS) on (Y page 62).
